1 Claim. 1

This invention relates to a putty applicator and has for its primary object the provision of a tool serving the dual function of applying putty to joints and smoothing the putty around the joint to produce a proper seal.

A further object of this invention is to provide a putty applicator of the character described having a bottom member which constitutes the smoothing tool which is so configurated that the putty when smooth will assume the proper angular inclination in the joint.

A still further object of this invention is to provide a putty applicator of the character described including a knife which can be employed both for applying putty to the joint and for moving excess putty from the top of the window frame or molding while the tool is being employed in the smoothing operation.

Yet another object of this invention is to provide a putty applicator including means for slidably and adjustably retaining the knife upon the smoothing tool so that the knife can be extended to any desired length or retracted entirely upon the smoothing tool when not in use.

These, together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the device, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure 1 is a side elevational view of the device as applied to a window and a supporting frame, the latter elements being shown in section;

Figure 2 is a longitudinal sectional view through the device;

Figure 3 is a sectional view taken substantially in a plane of section line 3-3 of Figure 2; and

Figure 4 is a fragmentary top plan view of the device employed in the smoothing operation.

Specific reference is now made to the drawings. In the several views in the accompanying drawings and in the following specification reference characters indicate corresponding elements throughout.

Indicated generally at Ill is a base member which is preferably hollow consisting of an upper wall I2 and a lower wall I4 interconnected by means of downwardly tapered side walls I6.

Secured to and extending longitudinally of the upper wall I2 of the base member is an inverted channel I8, the web portion of which is provided with a longitudinally extending slot 20. Slidable in the channel and upon the upper wall I2 is a 2 knife 22 which is further provided with a thread- .ed aperture 24 at one of its ends.

Fixedly secured to the upper surface of the web portion of the channel I8 is an elongated handle 26 by which the applicator may be moved from place to place. As shown clearly in the drawings, the handle 26 includes downwardly and inwardly inclined side walls 28 and an upper wall 30 having a longitudinally extending slot 32 which is in alignment with the slot 20 of the channel I8. It will be understood at this point that the handle 25 is bottomless.

Extending through the slots 32 and 20 is a threaded bolt 34 which is provided at its upper end with a handle portion 36. The free end of the bolt 34 engages the threaded aperture 24 in the handle 26 so that when the bolt is slid from end to end on the handle 26, the knife 22 will slide in and out of the channel I8. To adjust the knife 22 at any desired position relative to the smoothing base I 0, the bolt 34 may be turned further so that the free end thereof will press against the upper surface of the upper wall I 2 of the base In preventing further movement of the knife 22 relative to the base I0.

In practical operation, the knife 22 is extended to the position shown in Figure 2 and tightened, as mentioned hereinabove, in this position. Putty is then applied to the joint 38 between the window frame 40 and the pane 42 in the usual manner. Thereafter, the applicator is moved on the window pane so that the tapered sides I6 of the base II] will cause the putty 44 to assume the inclined position necessary to effect a proper joint. At the same time, if the knife 22 is allowed to be extended from the base In, it will be readily seen that the knife will remove excess putty from the top surface of the frame 40. Of course, the smoothing base I0 may be applied to the putty with the knife 22 retracted thereon. In view of the foregoing description taken in conjunction'with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the .invention as herein described and the scope of the appended claim.
